PAPER-BOX MACHINE.

SPEGIFIGATION forming part of Letters Patent No. 543,869, dated August 6, 1895.

Application filed October 10, 1892. Serial No. 448,318. (No model.)

To all whom it may concern:

Be it known that I, CLARENCE W. HOBBS,

a citizen of the United States, residing at Lynn, in the county of Essex and State of Massachusetts-have invented a new and use ful Improvement in Paper-Box Machines, of which the following is a specification, accompanied by drawings representing such parts of the mechanism of a paper-box machine as embody my invention.

My invention relates to that class of paperbox machines by which the outer surface of a paper box is covered with paper taken from a continuous roll and provided upon one side with a coating of adhesive material, the box to be covered being held upon a former, consisting of a block adapted to fit the inside of the box and support it in suitable position, while the strip of pasted or gummed paper is being applied to its outer surface. A machine of this class is described in the United States Patent'granted to W. Orr, J r., and G. F. Wright, dated August 13, 1867, and numbered 67,669.

My present invention relates to the device by which the former is supported, and it has for its object to provide a simple and efficient means by which a rotating former can be brought into alignment with a strip of paper to be wound about the sides of the box by the rotation of the former'and by which the position of the former can be changed and locked from rotation, while a strip of paper is applied to the bottom of the box, thereby allowing the sides and bottom of the box to be covered with paper without the removal of the box from the former.

. That part of a paper-box machine by which the roll of paper is gummed and presented in suitable lengths to be applied to the surface of the box held upon the former will be fully understood by those acquainted with the art of covering paper boxes, as such machines are now in use; and as that portion of the machine forms no part of my present invention I have not represented the same in detail in the accompanying drawings.

Figure 1 of the drawings represents in perspective view the former, upon which the paper box to be covered is held and the device by which the former is supported and shifted in its position, so as to receive gum med paper from either of the two strips presented by the machine. Fig.2 represents a front View of the box-supporting mechanism, showing the formerin position to receive the strip of paper applied to its sides. Fig. 3 represents the boxsupporting mechanism in front view with the former in suitable position to receive the strip of paper upon the bottom of the box. Fig. 4 is a top view of the box-supporting mechanism. Fig. 5 is a perspective view of a portion of the box-supporting mechanism representing the plate to which the former is attached; and Fig. 6 represents the latching-pin and its actuating-spring, with their inclosing barrel shown in sectional view on line 6 6, Fig. 4.

Similar letters refer to similar parts in the different figures.

Referring to the drawings, A denotes a portion of the framework, and B C the two strips of paper in position to be applied to the paper box. The mechanism by which the paper is gummed or pasted and the cutting mechanism by which the strips of paper are cut into suitable lengths to be applied to the box are not represented, but may be the same as that shown in the Orr and Wright patent, No. 67,629, or any known form of gumming and cutting mechanism now commonly used in machines of this class.

Held in lugs D D, projecting from the framework A and capable of sliding therein, is a rod D provided with a groove D to receive a spline D in the lug D, by which the rod D is held from turning. When suitably adjusted within the lugs D D the rod D is clamped in position by means of the set-screw D Capable of turning upon the end of the rod D is an arm E, provided at its free end with a socket E to receive the spindle F, having a plate F attached to one end and held in position in the socket E by means of a nut F G denotes a plate having a hub G by which it is attached to the rod. D and extending transversely across the rod with lugs G2 at either end, carrying the adj usting-screws G and Gr,- by which the angular movement of the arm E about the rod D is limited, the

screws being so adjusted that when the arm E is rocked about the rod D into the position shown in Fig. 2 the arm will be supported upon the adjusting-screw G and the spindle F will be held in a horizontal position, and when the arm E is supported upon the adjusting-screw G as shown in Fig. 3, the spindle F will be held in a vertical position.

To the plate F is attached a rectangular frame II, adapted to fit the inside of a paper box to be covered, and constituting the former. \Vhen the former H is brought into the position represented in Figs. 1 and 2 the box held thereon will be in alignment with the strip of paper 13, so the strip can be wound around the box by the rotation of the former, the spindle F rotating freely within the socket E. After the strip B has been applied to the outer sides of the box the arm E is rocked upon the rod D into the position represented in Fig. 3, bringing the former H into alignment with the strip of paper 0 and with the bottom of the box uppermost.

Extending upward from the plate G is an arm I, carrying at its upper end the barrel I, inclosing a cylindrical chamber I containing a spiral spring J and a vertically-sliding pin J, having a collar J attached thereto, against which the upper end of the spring J rests and by which the sliding pin J is forced upward, holding the collar J against the under side of the screw J held within the upper and screw-threaded end of the barrel 1 Attached to the under side of the plate F are the curved plates K, having'holes K to receive the upper end of the pin J, when the formeris carried into the position represented in Fig. 3, with one of the plates K resting upon the upper surface of the screw J thereby preventing the former from being rotated while the strip of paper 0 is being applied to the bottom of the box. The plate F is provided with two curved plates K K, so the former can be presented to the paper with either end foremost. The screw .1 can be raised or lowered, so the arm E, when in the position shown in Fig. 3, will rest upon the adjusting-screw G3 and allow the pin J to enter one of the holes K.

The change of the former H from one position to the other, as represented in Figs. 2 and 3, so that either of the strips of paper B or O can be applied to the box, is eflected by simply rocking the arm E upon the rod D the proper position of the arm being determined by the adjusting-screws G and G. In the position represented in Fig. 2 the former is capable of rotating freely about a horizontal axis, in order to allow the paper to be wound about its sides; but in the position represented in Fig. 3 the former is locked from rotation by the latching-pin J entering one of the holes K in the plates K.

The rod D is longitudinally adjustable in the lugs D D, so the position of the former can be varied with reference to the framework A.

In the operation of the machine the paper box to be coveredis placed upon the former H, and the former is brought into the position represented in Fig. 2. The free end of the paper strip B is then applied to the side of the box and the former rotated, winding the strip of paper around the sides of the box, the strip of paper as it is wound upon the box being drawn from a continuous roll supported in the framework of the machine, but not shown in the drawings, and passing over a gum roll L partially immersed in paste or a solution of gum contained in the gumbox M. The paper wound upon the sides of the box is then severed from the strip B by any'of the shearing or cutting mechanisms now in use in machines of this class, and the former II is then changed into the position represented in Fig. 3 by rocking the arm E upon the rod D one of the plates K being brought against the screw J", and the end of the pin J entering one of the holes K, thereby locking the former from rotation and presenting the bottom of the box in proper position to be covered by the strip of paper 0, which is drawn over the bottom of the box and cut off at the proper length.

The former is usually a frame or box, preferably of wood, and attached by screws to the plate F, and is readily exchanged for formers of difierent sizes made to fit the interior of the box to be covered.

What I claim as my invention, and desire to secure by Letters Patent, is-

1. In a paper-box machine, the combination With mechanism for presenting gummed or pasted strips of paper to be applied to the surface of a box, of an arm pivoted in a plane between said gummed or pasted strips and capable of a rocking motion by which its free end is brought into alignment with either of said gummed or pasted strips, a former carried by the free end of said arm and stops by which the rocking motion of said arm is limited, substantially as described.
